ABSTRACT:
Methods and devices are provided for controlling the impact of undesirable short circuits between non-adjacent but critically matched pairs of electrodes in a co-planar electrochemical sensor. In one embodiment, the size and/or shape of at least one electrode is configured to induce a short circuit between electrode pairs for which connectivity is pre-set to be measured by a meter in order to indicate a short circuit between a different pair for which such connectivity is not pre-set to be measured. In another embodiment, the surface area of one or more electrodes, other than the working electrode, which are designed to be exposed to a sample fluid is significantly limited in relation to the surface area of the working electrode that is exposed to the sample fluid.
